钙碱性玄武岩系列和拉斑玄武岩系列玄武岩具有低的REE含量和亏损的LREE配分型式，表明它是由LREE亏损和HREE略有富集的地幔部分熔融形成；

The REE of calc-alkali basalt and tholeiite are characterized by lower amounts of REE and LREE-depleted distribution pattern and which reflect that the basalts were formed by the partial melting of LREE-depleted and slightly HREE-rich mantle .

稀土分配平坦型的拉斑玄武岩（TH1）类似于洋壳，但与MORB显著不同，更象不成熟的大陆性火山弧。
